What caused it, and can it be fixed?
In our Apple (Mac) repair business we see this often and there are three main reasons this occurs.
Reason number one, software issues.
A failed software or Mac OS operating system update.
When updating your Mac we are prompted to "not power down" while updating. Interrupting a computer while updating can create corruption in the computer's system files. I can also be interrupted if you try to update, but have less than 35GB of free storage. MacOS operating system updates (from one version to another) require approximately 35GB of free space to run.
If you are a MacAir user and you see this while trying to update, there is a good chance it is because you did not have another free storage.
Reason number two
Hardware issues.
Folder with question mark, spinning wheel and no boot can also be sign of a failed drive. When drive failure occurs the system tries to find critical start up files but can't, resulting in the "folder question mark" error.
In older Macs the solution to this is to replace the bad drive, in new M1+ Macs things are much more complicated. Apple silicon Mac drives are integrated into the motherboard. Thus if the drive fails, often the solution is board repair, a new board, or a new Mac.
While some repair shops have been experimenting with chip swaps, taking the old drive chips off and replacing them with good ones, not many places do this kind of work.
The fact that Apple has moved to integrated storage for all of its systems, backing up one's data is even more important than before.
